Close to 1,000 Genesee Theatre patrons received an email Wednesday morning that singer Al Jarreau will not be performing a scheduled Feb. 24 concert in Waukegan.

The seven-time Grammy-award winning artist was hospitalized recently in Los Angeles suffering from exhaustion and has canceled his tour dates, according to a statement posted at his official website. Refunds are available at the point of purchase, said Colleen Rogalski, marketing and booking manager for the theatre.

Jarreau has not only canceled the rest of his 2017 tour, but he also is retiring from touring at the recommendation of his physicians, said his agent Joe Gordon Tuesday afternoon.

"Al is slowly improving, and said he wants to thank all his fans for supporting him and his music for the past 50 years," Gordon said.

Concerts rarely get canceled at the Genesee, according to Rogalski. "The staff was really excited about Al Jarreau coming. The patrons were enthusiastic. It's just a shame, but what a beautiful career to have had," she said.

Jarreau's last album was released in 2014 and paid tribute to his friend, George Duke, with whom he performed in the George Duke Trio early in his career.

He is known for such pop classics as "Mornin'" and "We're In This Love Together," as well as his jazz-style scat singing.

He grew up in Milwaukee and began singing at age 4.

Rogalski said Jarreau "bridged the gap between all different kinds of genres. He's made a name for himself in multiple genres. It's just lovely. He's a musician of music."

Indeed, Jarreau won Grammy awards for his jazz, rhythm-and-blues and pop singing.

"With complete sorrow, Al Jarreau must retire from touring," according to a press release submitted to the media by his management team Tuesday afternoon.

"He is thankful for his 50 years of traveling the world in ministry through music, and for everyone who shared this with him — his faithful audience, the dedicated musicians, and so many others who supported his effort."
